Concept and Functions of a Presentation

Presentation is a form of visual information delivery aimed at conveying a specific message to an audience using various media tools.

Main functions of a presentation:

• Informative — delivering facts, data, and analytical information.
• Educational — facilitates learning and explaining complex concepts.
• Persuasive — aimed at shaping or changing the audience’s opinion.
• Image-building — showcasing professionalism, authority, or prestige.
• Motivational — encouraging action, change, or decision-making.
• Advertising/Marketing — promoting products, services, or brands.

History of Presentation Technologies

Early Forms:

• Posters and slides.
• Overhead projector.

Analog Era:

• 35mm slides and overhead projectors (1970s–80s).

Digital Revolution:

• PowerPoint (1987), Keynote, Prezi, Google Slides, Canva.

Modern Stage:

• Animations, interactivity, infographics, videos, VR/AR, cloud technologies.

Purposes of Presentations in Scientific, Educational, and Business Environments

Scientific Environment:

• Presentation of research findings.
• Hypothesis justification and thesis defense.
• Conference presentations.

Educational Environment:

• Explaining new topics and visualizing learning material.
• Increasing student engagement.

Business Environment:

• Presenting projects, reports, strategies.
• Negotiations, marketing, staff training.

Psychological Aspects of Audience Perception

• Short-term memory capacity — ideally 5–7 elements per slide.
• Visual dominance — images are perceived better than text.
• Emotional perception — emotions enhance memorization.
• Color perception — color affects attention and mood.
• Cognitive load — overload hinders learning.
• Primacy and recency effect — key ideas are best remembered at the beginning and end.

Principles of Visual Design

• Color — should match the theme, evoke appropriate emotions, and ensure good contrast. Preferably use no more than 3–4 main colors.
• Font — should be readable and consistent. Optimal size: 24–32 pt for body text. Sans-serif fonts like Arial or Calibri are recommended.
• Composition — key information should be logically and hierarchically placed. Use grid systems, alignment, and balance principles.
• Animation — used moderately for emphasis and step-by-step content. Avoid excessive effects and distracting transitions.

Technical Requirements for a Quality Presentation

• Optimal file size — should not be too large to open or share.
• Format support — use universal formats (PPTX, PDF) for compatibility.
• Image resolution — at least 1280×720 pixels. Avoid pixelation.
• Error checking — no spelling, logical, or visual errors.
• Display flexibility — suitable for computers, projectors, tablets.
• Backups — copies stored on flash drives, cloud, email.

Use of Multimedia Elements

• Video — helps demonstrate processes, interviews, ads. Use short (1–2 min) and relevant clips.
• Audio — can enhance emotional effect (music, sound effects, voiceover). Use carefully and consider room acoustics.
• Interactive elements — navigation buttons, hyperlinks, embedded polls and forms. Especially useful in educational and marketing presentations.
• GIF animations — used for short, looping actions when video is unnecessary.

Structure of an Effective Presentation

A well-structured presentation should have a clear and logical flow that allows the audience to follow the material sequentially without overload.

• Introduction — purpose, relevance, problem statement. Sets the tone and grabs attention.
• Main part — key ideas, data, arguments. Organized from simple to complex or problem–solution format.
• Conclusion — summary, conclusions, recommendations, call to action.

Principles of Conciseness and Clarity

• Conciseness — each slide should convey only one main idea. Use short phrases, keywords, bullet points.
• Clarity — prioritize visuals: diagrams, charts, icons, photos instead of plain text.
• One idea — one slide — helps maintain attention and avoid overload.
• Simplification — avoid complex language, jargon, and excessive details.

Practical Tips for Slide Design

• Use a grid and align elements for neatness.
• Maintain a consistent design style (color, font, background) across all slides.
• Headings should be brief and informative.
• Optimal text volume — up to 40 words per slide.
• Use high-quality, context-relevant images.
• Number slides to simplify navigation and references.
• Test the presentation on different devices in advance.

Common Presentation Mistakes and How to Fix Them

• Too much text — audience stops listening and starts reading. Solution: use keywords and visuals.
• Small font — hard to read, especially from a projector. Solution: use at least 24 pt font size.
• Excessive animation — distracting and slows down perception. Solution: use animation only when necessary.
• Unclear structure — loss of logic, hard to follow. Solution: follow the classic structure: intro – main – conclusion.
• Poor text-background contrast — makes text unreadable. Solution: use dark text on a light background or vice versa.
• Ignoring the audience — generic delivery without considering the listeners. Solution: adapt content to the target group.

Analysis of Successful and Unsuccessful Presentations

To understand the key success factors of presentations, it’s helpful to compare good and bad examples.

Signs of successful presentations:

• Clear structure: introduction, logical development, conclusions.
• Visual clarity: graphs, diagrams, illustrations.
• Good visual style: harmonious colors, readable fonts, aligned elements.
• Minimal text, maximum informational value.
• Emotional engagement, storytelling, audience interaction.

Signs of unsuccessful presentations:

• Overloaded with text and data.
• Inconsistent style and color scheme.
• Complex, unclear diagrams.
• Lack of logical flow in the content.
• Small fonts, poor contrast, inappropriate background.

Audience Survey on Presentation Perception

To evaluate how presentations are perceived, you can use a target audience survey.

Example survey questions:

• How easy was it to understand the information?
• What did you like/dislike about the design?
• Did the presentation have a logical structure?
• Were the visual materials useful?
• Did the presentation leave a positive impression?

Collecting feedback helps improve structure, delivery, and design of future presentations.

Creating Your Own Presentation Based on Quality Criteria

Based on the studied material, a presentation was created that meets the following criteria:

• Structure: introduction, main part, conclusion.
• Consistent visual style and color palette.
• Visual elements: images, graphs, infographics.
• Moderate use of animation.
• Clear headings and logical slide sequence.
• Adaptation for the target audience.

The presentation was made with consideration for technical requirements and information perception principles.

Evaluating the Effectiveness of the Created Presentation

To assess effectiveness, the presentation was demonstrated and feedback analyzed.

Evaluation criteria:

• Audience engagement level.
• Understanding of key ideas after viewing.
• Visual perception ratings (color, design, readability).
• Alignment with presentation goals (inform, persuade, educate, etc.).

Based on the feedback, the presentation was improved: reduced text volume, enhanced visuals, improved conclusion structure.
